Extensor & Supinator Muscles Explained — Forearm Anatomy for Artists #figuredrawing #samysketcher

Understanding the extensor and supinator muscles of the forearm is essential for artists who want to draw arms with accuracy, rhythm, and believable structure. In this video, I’ll break down the key forms, functions, and placements of these muscles. You’ll learn how the extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris, and Supinator muscles all interact when the wrist and forearm rotate, extend, or relax. I’ll also demonstrate how to identify these muscles in different arm positions and simplify them into clear, drawable shapes that make sense for figure drawing. Whether you’re sketching from life, imagination, or photo reference, understanding this area will help you: This lesson is part of my ongoing SamySketcher anatomy series for artists — covering the arm from the shoulder girdle to the wrist, step by step. Perfect for beginners learning structure or advanced artists refining their understanding of muscle rhythm. Stay tuned for future videos covering the flexors, along with simplified shape breakdowns for dynamic figure drawing. --- *Tools Used:* 🖋 Clip Studio Paint 🎥 OBS Studio 🎧 DaVinci Resolve for editing --- -- *Follow SamySketcher:*    / @samysketcher   --- forearm anatomy for artists, extensor muscles drawing, supinator anatomy, how to draw arms, anatomy drawing tutorial, figure drawing, artist anatomy, forearm muscles explained, art education, art fundamentals, drawing muscles simplified, samysketcher anatomy series, how to draw realistic arms, muscle structure for artists, gesture drawing arm study
